Need help.

[ez]

I really do not know what catagory I should put this thread and ask help from someone who knows PHP function.

1. A function which takes a string as a parameter and replaces all entries of one symbol with another. The function will look something like:

function replacechars(string, char1, char2);

i.e. if we give it three input parameters: "Welcome" letter "o", "O"
It will return the string: "WelcOme"

2. Another function returns "1" in case if a substring found in a string, otherwise "0" returned. Ideally the function will return a number of entries.

function scanstring(string, substring);

I am not sure if predifined functions already exist.

Thanks in advance.

1:
$strNew = str_replace("o", "O", "Welcome");

2:
since you want 1 or 0 you can do this:

function scanstring($strexp, $substring)
{
return (strstr($strexp, $substring)==$substring?1:0);
}

for the first one it's a little complicated, you have to loop the string.
